I don't think mine flies much different than my 1/4 Sukhoi or Extra.
The old 21 is lighter and not as 'beefy' as the newer 'Edges' and 232's so it doesn't require the power but, I don't think it snaps any worse than the others.
Keep the CG right-on or slightly forward and it's a great aerobat.
It was my first low-wing about 13 years ago!

Good luck!!! Kirk
